Airflow vortex superfine pulverizer      

  First, the main purpose:

Airflow vortex superfine pulverizer for food (corn, rice, ginger, pepper, pepper, oil wheat, soybean, star anise, cinnamon, dehydrated vegetables, hawthorn, dried ginger, onion, garlic, chives, carrots, soybean meal, plant fiber , starch, fish meal, flavors and fragrances, chitin, cabbage, grain, shrimp, condiments, spices, ginseng, American ginseng, agricultural and sideline products, yam, rehmannia, spinach), chemicals (dyes, pigments, coatings, pesticides, white carbon) , black carbon, algae, bentonite, ceramic glaze), pharmaceutical, feed, calcium carbonate, Chinese herbal medicine and other low-hardness materials.

 

Second, the structure and working principle:

The airflow vortex superfine pulverizer is composed of a main machine, a pulse dust collector, a high-pressure centrifugal fan, a wind shut-off device, a cyclone separator and an electric control cabinet. The main body is composed of a body, a frame, a discharge pipe, and a transmission device (motor, stepless). The speed reducer), the automatic feeder and the crushing chamber are composed. The crushing chamber is equipped with a main working part such as a classifying device, a ringing ring and a crushing knife. The automatic feeder pushes the material into the crushing chamber, and enters the crushing chamber due to the negative pressure. The material is punched and sheared by the pulverizing knife at high speed, and the pulverized material enters the grading wheel due to the negative pressure, and the fineness is controlled by the rotation speed of the grading wheel. The low-temperature superfine pulverizer produced by Fenghua Pharmaceutical Machinery is a vertical-axis reflection type micro-grinder, which can simultaneously complete two processing steps of micro-grinding and fine powder sorting. It consists of the body, the frame, the feeding device, the pulverizing device, the discharging pipe, the transmission device and the motor. The internal structure is shown in the figure. The complete set of low-temperature superfine pulverizing units is composed of main engine, dust collector, high-pressure centrifugal fan, air shut-off device, cyclone collector and electric control cabinet. The inner cavity of the machine is cylindrical, divided into upper and lower parts by a ring, the lower part is an air inlet chamber, and the upper part is divided into a crushing chamber and a classifying chamber by a diverter ring. The crushing chamber is composed of a pulverizing disc and a bushing, which is used for crushing the fine powder, and the grading chamber is composed of a classifying impeller, which can divide the fine powder into two specifications of the particle size standard and the non-standard product, and the standard product is sucked out through the discharge pipe. The product is collected by a cyclone collector. The non-standard product falls back to the crushing chamber along the inner wall of the split ring and continues to be crushed until it reaches the standard. The low-temperature superfine pulverizer produced by Fenghua Pharmaceutical Machinery has the function of water cooling, low temperature rise during pulverization, uniform particle size, fineness of 80-2500 mesh, and is different from ordinary superfine pulverizer.

 

The WFJ series B-type micro-crusher is based on the original A-type pulverizer to improve the development trend of the user's requirements for fine powder pulverization. The main differences are as follows: 1. The pulverizing disc and the classifying impeller of the A-type pulverizer From the concentric shaft drive to the independent bearing housing unit, the adjustment range of the staged impeller can be improved; 2. The axial distance of the crushing bearing seat is lengthened, so that the stability of the equipment at high speed can be greatly improved. . WFJ series C-type pulverizer changes the electromagnetic speed-regulating motor of B-type pulverizer into frequency conversion speed-regulating device. Compared with grading feeding motor, it can save about 30% of electricity, meet the requirements of high-grade users, and has more compact structure and more convenient adjustment. Use more reliable advantages. The speed of the graded impeller is adjustable to adjust the product size. The feeding screw is placed on the side wall of the machine body to feed the material into the crushing chamber, and the rotation speed can also be adjusted to control different feeding amounts. The dust-laden air separated by the cyclone separator enters the dust-removing box, and the flow velocity suddenly drops due to the sudden expansion of the airflow volume. The larger dust of the particles has its own weight, and settles from the dust-containing airflow into the lower tank ash bucket. The remaining dust particles are hindered to the outer wall of the filter bag due to various effects such as hooking and static electricity of the filter bag. The dust-containing gas is purified through the filter bag and discharged from the air outlet of the box through the venturi. When the dust particles outside the filter bag increase continuously, the resistance of the dust collector is also increased. In order to ensure that the resistance of the dust collector is controlled within the specified range, the pulse controller sends a signal to open the solenoid valve to compress the air bag. Air (called secondary air) enters the filter bag. As a result, the filter bag expands instantaneously, and the impact of the reverse pulse airflow quickly disappears, and the filter bag shrinks sharply. Thus, the expansion and contraction causes the excess dust particles accumulated on the outer wall of the filter bag to be shaken off, and the fallen dust is discharged through the ash discharge system to clean the filter bag.
